Abstract

Introduction: Stool form and its frequency are associated with different gastrointestinal diseases. However, in clinical practice it is not easy to obtain appropriate information about the defecation pattern. The use of a graphic scale can be an effective tool to characterize the appearance of the stool. Because of this, the Bristol Stool Form Scale was developed and validated for approximately two decades. This scale consists of images which represent seven types of stools associated with accurate descriptions according to their shape and consistency, using readily recognizable examples. The patient should only select the type of stool that is most similar to yours. In the pediatric population, the modified Bristol Stool Form Scale for Children (mBSFS-C) was recently created. This scale proposes to reduce the number of types of feces from seven to five types, in order to facilitate discrimination to be performed . The use of this scale has been validated for children aged 6 to 8 years old when the descriptors are read aloud, and for children over 8 years, without the aid of reading the descriptors. In Brazil , the Bristol Stool Form scale has been translated and submitted to cultural adaptation to Brazilian Portuguese. However, mBSFS-C still needs to go through this process so it can be used in the pediatric population in our country. Objective: The aim of this study is to perform the translation, cross-cultural adaptation and validation of the Bristol Stool Form Scale for Children for Brazilian Portuguese. Methodology: This project consists of two parts: the translation and cross-cultural adaptation of mBSFS-C for Brazilian Portuguese and then the translated version will be applied to a population of Brazilian children, for the validation. A party of 240 children, aged between 6 and 18 years old, without any cognitive deficiency will participate of this study. These children will be recruited among patients of the Pediatric Clinic of the Botucatu Medical School's Hospital. At this moment, a framework will be presented with drawings representing the five types of stool forms of mBSFS-C. After that, children will be asked to correlate a text, selected randomly from the translated scale, with the drawing that represents the type of stool described in the text. Subsequently, the Brazilian portuguese translated version of mBSFS-C will be presented and children will be requested to point which type of stool is more similar to theirs. Ten percent of respondents of each group will be instructed to repeat the assessment 15 days later (retest), to test the reproducibility of the scale.
